Mount your distribution as read-only on the container, so that you get
instant code reload.

However, those two things conflict, as the container can’t write to the
read-only file system. You could drop this constraint and allow the container
to write to the directory, but this .egg-info directory wouldn’t be owned
by you, which will lead to other problems.

This plugin is a workaround to this issue: It generates the .egg-info in the
host system, even before the image is built.
